The first option ,f^-1(x)=1/2*x-1/2

Step-by-step explanation:

f(x)=2x+1

y=2x+1

Interchanging the places of x and y, we get,

x=2y+1

(x-1)/2=y

f^-1(x)=(x-1)/2

f^-1(x)=1/2*x-1/2

The first option.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
